Abstract: |
Given a Riordan array, its vertical half and horizontal half are studied separately before. In the present paper, we introduce the $(m,r,s)$-halves of a Riordan array. This allows us to discuss the vertical half and horizontal half in a uniform context. As applications, we find several new identities involving Fibonacci, Pell, and Jacobsthal sequences by applying the $(m,r,s)$-halves of Pascal and Delannoy matrices. |
